This invention relates particularly to flashlights of the type whichpermit the lamp to be turned at an angle to the axis of the Y casing,when desired. n

'5 The primary object is to provide a thoroughly practicable flashlightof the character indicated which is of staunch and durable character,and which serves effectively as an ordinary flashlight, but which, by asimple manipulation, may be changed to enable the axis of the lamp to beset at an angle to the axis of the main casing. l

The invention is illustrated in a preferred embodiment in theaccompanying drawings,

` in which- Fig. 1 is a broken vertical sectional View of a flashlightembodying the invention Fig. 2, a transverse section taken. as indicatedat line 2 of Fig. 1, and Fig. 3, a detail elevational view of thesupport which carries the tiltably mounted head employed.l

In the illustration ofthe invention given in the drawing, A designatesfa main casingsectionv equipped with an extension-,section A B, alamp-carrying headmounted ony a bracket B `which is pivotally supportedon a short standard B2 carried yby a'support B3 detachably connected,with the upper end ofthe main casing-section A; and @,a'batcomprising adry cell, vor dry cells, housed within the main casing-section.

' The casing-section A is shown equipped at its lower end with aremovable cap l within which is located a spring 2 which formselectrical connection between the Zinc bottom of the lowermost cell andthe casing. p

The upper end of the casing-section A is provided, as indicated vat 3,withl a corrugated thread-portion.

.The casing-extension A bular member having its upper. end abuttingagainst the lamp-carrying member B, and having its lower end lprovidedwith a corrugated thread-poi'tion 4 which engages the '45 thread 3. Thecasing-extensionA may be screwed downwardly until the thread-portion 4becomes disengaged from the threadportion?) of the main section, and theextension A may then be slid downwardly into telescoped position toenable the head B to ber. comprising a comprises n a tube turned at anangle to the axis of the flashlight casing.

The lamp-supporting head B is shown as consisting of a cupped havingvitsbottom provide-d with a central opening equipped with an insulation ring5 in which is supported a metal lamp socket 6.

sheet-metal member i The outer open end of the cupped inember' Bpreferably is provided with acorru- 1;

gated thread-portion 7, upon which is adjustably mounted a focusingsleeve 8 which carries a reflector 9 and a glass-disk, or lens 10. rl`hebottom of the reflector 9 is provided with a perforation 9a throughwhich the lamp bulb 11 mounted in the socket 6 protrudes into thereliector. Focusing, where this feature is desired, may be accomplishedby the means disclosed.

The lamp socket 6 is provided with a de- 3 pending extension 6a in thelower end o which is fitted an insulation disk l2 through which extendsa contact 13 with which is connected a conductor 14.

The bracket B is shown as a furcated memhead portion 15 which conformsto the kpart-spherical bottom of the member B and is secured thereto,asby means of rivets 16. Y y i V The bracket B2 comprises a sheet-metal`strip bent into suitableform and secured to the member `B3V as by meansof rivets '17. Furcations of the member B embrace the standard portionof the member B2, and the serves as a pivot. The connection preferablyis sufficiently tight tol .develop a suitable amount 'of friction sothatthe head B will remain at any desired angle at whichit may be set.

The support B3 lis shown as comprising a sheet-metal disk 19 having aflange 19B which is corrugated to form a thread which engages thethread-portion 3 of the main casing-section; and an insulation disk 20secured to the disk 19, the disk 19 being provided with a centralopening which is covered by the insulation disk 20. Through theinsulation wire 14.

parts are firmly connected by a rivet 18 which p disk 2O extends acentral contact 21 which is electrically .connected with the The batteryC is shown as comprising two dry cells 22 having central contacts orelectrodes 22a, the central electrode of the upper cell making contactwith the central contact 21, and thus being electrically connected,through the medium of the wire 1li and the contact 13, with the centralcontact 23 of the lamp.

The metal socket 6 makes contact with the outer terminal of the lamp.This socket is electrically connected at 24 with an insulated wire 25which extends through an insulation ferrule 26 with which the disk 19 isequipped.

The lower or inner end of the conductor 25 affords a contact 25@ whichmakes contact with the upper end of a conductor 27 (suitably insulated)which is connected with the casing, the conductor 27 leading to theswitch 28 which is equipped with a sliding switch member 29 electricallyconnected to the casing and adapted to close the circuit at the point30.

Preferably, the member B3 is equipped with a pivotally mounted foot, orsupport, 31, which normally is housed within the casingscction A.

The member 31 is shown as consisting of a wire bent into suitable shapeto provide feet 31" and pivotsportions 31h, the pivot-portions extendingthrough pivot-members 32 and riveted thereat, these connectionspreferably being sufficiently tight to hold the member 31 in any desiredposition of adjustment.

After the sleeve A has been completely telescoped on the mainkcasing-section A, the support 31 may be swung in one direction toprovide a protruding foot or support, and the 1amphead B may be swung inthe opposite direction. Thus, for example, the pivot support 31 maysupport the flashlight on its side, while the lamp is directed laterallywith relation to the flashlight body. That is, the flashlight body mayrest on its side with one end supported on the member 31, while the lampis directed upwardly.

When the flashlight is in use as an ordinary flashlight, thecasing-'extension A is in the position shown in Fig. 1, in which itfirmly supports the lamp-head B and houses the internal' connections. Inthis condition, the flashlight has much the appearance of an ordinaryflashlight, perhaps of special construction. On the other hand, thesleeve A may be caused to telescope fully with the upper portion of themain-casing section A of the flashlight casing, thus permitting the lampto be. turned at an angle to the body of the flashlight and supported asexplained above.

The pivotal support 18 of the lamp-head B is eccentrically located, asshown in Fig. 1. That is, the pivot is shown located near one side ofthe casing, and this is the preferred arrangement.

While the invention is shown applied to a flashlight in which oneterminal of the lamp is grounded on the casing, it is obvious that anyother desired arrangement may be used; and, if desired, a non-metalliccasing may be employed, in which event suitable circuit connections maybe provided in a manner well understood in the art.

The foregoing detailed description has been given for clearness ofunderstanding only and no unnecessary limitation should be understoodtherefrom, but the appended claims should be construed as broadly aspermissible, in view of the prior art.
